Since 2018, he has been the vice dean of the school. Since 2020, he has been Specially Appointed Professor of Chang Jiang Scholar Program of China. His research interests include short process of utilization of complex iron ores, agglomeration and direct reduction of iron ores, efficient and clean utilization of solid wastes, extraction of rare and scattered metals, synthesis of functional mineral materials, and processing of low-grade aluminum- and silicon-bearing resources. He has published over 200 papers and 4 books and won two Second-Class Prizes of National Scientific and Technological Progress Award of China. Tao Jiang is a professor in the School of Minerals Processing and Bioengineering at Central South University, China. He received his M.S. degree in 1986 and Ph.D. degree in 1990, both from Central South University of Technology. Then he joined the university and served as an assistant professor (1990-1992) and full professor (1992-now). From 2000 to 2003, he was a visiting scientist to the Department of Metallurgical Engineering, the University of Utah. He has been Specially Appointed Professor of Chang Jiang Scholar Program of China since 2008 and dean of the school from 2010 to 2018. His research interests include agglomeration and direct reduction of iron ores, and extraction of refractory gold ores. He has undertaken more than 50 projects from the government and industry, including the National Science Fund for Distinguished Young Scholars Program. He and co-workersinvented the direct reduction process of composite binder pellets and three plants were set up in China based on the invention. He proposed the innovative composite agglomeration process of iron ore fines, which was put into production in Baotou Steel Company, China. He has published 320 technical papers and 6 books. He holds 35 patents and has more than 30 conference presentations. Mingjun Rao is an associate professor in the School of Minerals Processing and Bioengineering at Central South University, China.
